Kotlin Multiplatform App Development
Imagine preparing a pizza. You have a recipe that works in both an oven and an air fryer. The core ingredients are the same (like the KMP code), and each appliance has specific settings to get the pizza just right (in our case, iOS and Android). When the pizza is done, it might have slightly different textures, but it’s still the same delicious pizza at its core.
It is the same for Kotlin Multiplatform technology. Using KMP, the app will maintain its core functions across platforms (pizza recipe), but it can be customized to meet iOS and Android users’ expectations, making it feel native and intuitive on each platform (crispier in the air fryer and more precisely baked in the oven). Instead of writing separate code for each platform, developers have a single codebase for shared business logic.
Kotlin Multiplatform is great for reducing development time since you don’t need a separate developer for Android and another for iOS; one person can write shared logic in Kotlin that will work natively on both platforms. It also reduces development costs since updates and bug fixes need to be made only once and there is no duplication of work.
Native development generally incurs higher costs because it requires separate codebases for Android and iOS. If your application has very specific requirements for platform-specific features and needs to be as precise as possible (such as advanced camera functionalities, certain sensors, etc.), then native development is a good choice.
Kotlin Multiplatform uses Kotlin as a programming language, which means that Android developers can easily implement their knowledge to develop cross-platform applications. On the other hand, Flutter has its own, not quite familiar language, Dart. Flutter is owned by Google, and KMP by JetBrains, but lately, Google announced support for Kotlin Multiplatform due to its big potential and stability.
Both frameworks have their pros and cons, but generally perform well and save you time and money. It can be that if you need an app quickly, it is more feasible to use KMP because Android developers are already familiar with Kotlin, as it is their primary language even when developing native apps.
React Native allows developers to write apps using JavaScript and React, rendering components natively for both iOS and Android, which can lead to a more web-like development experience. By allowing the usage of native UI components and letting developers exchange Kotlin code across platforms, KMP, on the other hand, makes it easier to integrate platform-specific features and performance.
Maybe this will help you make a decision: We had an experience with a client who wanted us to translate his app from React Native to Kotlin Multiplatform. His feedback was, “I don’t know what you did, and I can’t tell you the exact difference when using the app, but I can feel it is different.”
Many factors impact the cost of developing a mobile app, but we will list here the main ones:
- App complexity: Basic apps may range from $15,000 to $50,000, while complex apps can exceed $100,000.
- Development team: Costs can vary based on developers’ proficiency in Kotlin and KMP, the team’s location, whether you hire freelancers or a mobile app development company, etc.
- Timeframe: Typical timelines for KMP projects can range from 3 to 6 months or longer, depending on the app's complexity. Developers from Aetherius Solutions managed to deliver the app to the client in just one month because the client had a specific request to see the basic features on the screen (login screen, navigation bar).

Kotlin Multiplatform Services: Simple Explanations for Non-Techies
Cross-Platform API Integration
Imagine cross-platform API integration as a universal remote control for TV, gaming console, and sound system. You want to take control of them with just one remote - in our case, this remote is API (Application Programming Interface).
Our developers create an app that works on both Android and iOS devices, and they need API to connect it to various services, like payment systems, social media, or weather data. This way, the app works well on multiple devices without having to build separate connections for each platform, making the process faster and more efficient.
Platform-Specific UI/UX Design
By writing a single code, you get a native UI/UX design that meets user expectations on each platform. For example, Android users might prefer certain button styles or color schemes that differ from what iPhone users like.
In order to optimize user satisfaction and engagement, our platform-specific UI/UX design solution in KMP makes sure your app not only functions smoothly but also looks great and feels comfortable for users on both iOS and Android.
Native Feature Integration
As part of our Kotlin Multiplatform services, integrating native features means connecting your app to the unique capabilities of each device, like the camera, GPS, or push notifications, in a way that feels natural for users on both Android and iOS.
Also, adding new features and making updates is easier with KMP since it allows us to share much of the code across platforms.

How Good Is Kotlin Cross-Platform?
By eliminating the need for separate teams, you need fewer developers and hours to build your cross-platform app. This leads to savings of approximately 30-50% in development costs compared to the native approach. It is an especially suitable option for startups with limited budgets.
You can have your MVP faster and, therefore, start validating your idea much faster than if you were waiting for a separate MVP version for each platform. If you want to see on the screen the most basic features such as user authentication, we can deliver that to you in just 2 weeks!
It is cheaper to maintain a Kotlin Multiplatform app since there is only one business logic code to keep an eye on. All updates, bug fixes, and new features are implemented in one place.
There is no need to write separate code for each platform; the same business logic is used to write a code once and run it both on iOS and Android.
People sometimes worry that Kotlin Multiplatform won’t provide a native experience as traditional native development. There is no need to worry - KMP allows direct access to each platform’s unique features and APIs, so your app’s functionality will be just as responsive as a fully native one.
Our developers can reuse the existing native code where needed, which is even easier if you already have an app written in Kotlin. This transition process is straightforward, allowing you to start by integrating shared logic while keeping your existing platform-specific UI.
